Sushi is delicious. There's a variety of different kinds, but certainly everyone has his or her favorite. And if you do the math, you should be able to deduce the most popular kind of sushi in Japan. So let's do that. Math. Nari Nari reports that Asahi polled 830 people across Japan (443 men and 387 women) over the age of 20 about their favorite kind of sushi. Out of all those polled, here are the top three replies: 3. Red Tuna (maguro akami or まぐろ赤身) at 8.8 percent 2. Salmon at 9 percent 1. Medium-Fatty Tuna (chutoro or 中とろ) at 15.3 percent. Other types of sushi followed in popularity, such as fatty tuna, uni, ikura, and so on. If you dig into the numbers, things get even more interesting. For men, the post popular sushi was medium-fatty tuna at 18.4 percent, while for women, the post popular sushi was salmon at 12.3 percent. And then if you break it down by area, medium-fatty tuna is the most poplar in the Kantou region (Tokyo), the Chubu region (Nagoya, Shizuoka, Niigata, etc), and the Kinki region (Osaka, Kobe, Kyoto). However, in the northeastern part of the country and in Hokkaido, the most popular kind is fatty tuna. In Kyushu, the most popular kind is uni, while in Hiroshima and Shikoku, there's a tie in popularity between hamachi, uni, and salmon. Digging even further, the most popular kind of sushi people first order when they sit down at a sushi restaurant is red tuna, using it as a barometer of sorts to see how good the restaurant's sushi is! Then the most popular sushi for people's last order of the meal is tamago, saying it's a nice way to end a meal. We actually didn't do any math—Asahi did. Thanks, Asahi! But there were numbers and raw fish, so hopefully that's enough for you, dear reader. My favorite kind of sushi is probably fatty tuna or salmon, depending on my mood (or in the case of pricey fatty tuna, my wallet). What about you?

On the menu, it's even located between traditional sushi like "uni" (sea urchin roe) and "negitoro" (tuna and green onions). Most people online could not believe that ice cream sushi actually exists. It's somewhat baffling!

Ice cream is traditionally served at conveyor belt sushi restaurants. Those chain restaurants are relatively inexpensive and frequented by families. Little kids often want ice cream for desert—thus, frozen treats. However, the ice cream is usually served in bowls (see above) and not as sushi. This is highly peculiar for Japanese people, too.

The odd thing is that ice cream sushi isn't exactly brand new. It seems to have exists for the past few years. There is at least one example of a small, local restaurant in Mie Prefecture serving it, too. You can see an image of that below:

That being said, this is still rather uncommon!

So how does ice cream sushi taste? The reaction seems to vary from "pretty bad" to "better than you'd think". Nintendo fan site Segment Games recently sampled the ice cream sushi, writing, "When I timidly tried ice cream sushi, surprisingly, it was perhaps not so bad." The site added that the green tea ice cream flavor was followed by the taste of vinegared rice and that you couldn't really taste the nori. Oh. If Japan has seen chocolate banana sushi, then why not ice cream sushi?

You certainly won't be able to order this at most sushi restaurants in Japan, but if you are feeling adventurous, you can always make your own.

Goodness! Just when you thought unusual sushi couldn't get any more, well, unusual, there's this: Caramel banana sushi. Starting tomorrow, conveyor belt sushi chain Kura is offering it in Japan. Remember, sushi rice is made with vinegar. Caramel is sweet. Then, there are bananas to contend with. All at once. In your mouth. This is very unusual. I think it's odd, you think it's odd, and you bet many people in Japan think it's odd. "This looks awful," wrote one commenter on GirlsChannel. "No way would I eat this." (On other forums, however, there have been a handful of Japanese commenters who seem keen.)Here is what the real deal looks like:But... is the caramel banana sushi any good? Courtesy of Entabe, here is celebrity Aya Ueto giving the dish a try earlier today:And...?Well then! As we previously covered, Kura is the same sushi chain that offered chocolate sauce banana sushi. Bananas, indeed.

Over the years, I've had some truly delicious sushi in Japan. Ditto for outside of Japan. Of course, there are the types of sushi created abroad, such as the California roll. Good stuff!Recently, a thread popped up on 2ch, Japan's largest online forum, showing a collection of "foreigner made sushi." The original source, a Russian website, is a few years old, but nobody on 2ch seemed to mind. However, some did mind the sushi. "This is not 寿司 (sushi)," stated one 2ch user. "It's 'sushi.'" And I'll admit that I've never had anything, that has looked like this. But hey, that's okay. Sushi should be flexible and open to interpretation."Their ability to pack rice for sushi is clumsy," professed a 2ch user. The way the rice is packed is incredibly important for sushi (and rice balls, for that matter). So, if there is one valid criticism, it's probably this. But, like most things, with practice, one can improve.Not everyone was so negative! "[The sushi] sure is creative," wrote another 2ch user, while another astute 2ch user pointed out, "Japanese people totally change foreign food when they make it, so you can't really say too much." A few others stated that the sushi actually looked yummy.Foreigners living in Japan know that the country's restaurants and chefs can offer their own spin on global cuisine. Some can even replicate it perfectly. Others fail horribly.Even in Japan, restaurants serve, and have served, sushi that can hardly be called traditional. Last month, nationwide conveyor belt sushi chain, Kurazushi (くら寿司) offered "chocolate banana roll sushi" as a Valentine's Day themed treat. You can see it below:Many of these chain restaurants, which appeal to families with little kids, have an array of untraditional sushi. Take salmon with melted cheese and mayo, for example. Cheese with mayo (or basil) is a relatively recent addition and would've miffed Japanese dinners in the past. Kids now grow up eating that kind of stuff.Whether that's video game-inspired sushi or the now iconic California roll, foreigners should feel free to experiment with their own take on sushi and create dishes to suit local tastes. Why? Because Japanese cooks are doing the same with international cuisine.
